岗巴地区位于西藏南部,属喜马拉雅东段,构造上处于印度板块北缘。区内白垩系发育较好,化石丰富。1903～1904年,印度地质调查所海登(H.H.Hayden),对区内白垩系作了较详细的调查,对地层进行了初步划分。1916年,杜维叶(H.Douville)研究了海登在岗巴地区所采集的菊石,对地层时代进行了讨论。自1963年以来,西藏地质局所属地质队曾在本区进行过剖面研究。1966—1968年,中国科学院西藏科学考察队再次对本区白
Gangba region is located in southern Tibet, is the eastern section of the Himalayas, tectonic on the northern edge of the Indian plate. The Cretaceous in the area is well developed and rich in fossils. From 1903 to 1904, H.H.Hayden, Indian Geological Survey, conducted a more detailed survey of the Cretaceous in the area and preliminarily classified the strata. In 1916, H. Douville studied the ammonites collected by Hayden in the Gamba area and discussed the stratigraphic age. Since 1963, geological teams affiliated to the Tibet Bureau of Geology have conducted cross-section studies in this area. From 1966 to 1968, the Tibet Science Expedition of the Chinese Academy of Sciences once again turned the area white
